Intermittent Fasting – Why?


According to many studies, intermittent fasting may help improve blood pressure, reduce liver fat, and lower cholesterol. The main reason for this practice is mainly for weight loss. Why? Well, in theory, there’s an exchange of sugars in the body for energy that happens during intermittent fasting that could cause a person to lose weight by creating a calorie deficit.  

When you deprive your body of calories, the body will go into a temporary state of starvation. This in effect slows your metabolism and forces the body’s fat cells to release glucose stored as energy to fuel your body. By doing this, a calorie deficit in attained – leading to weight loss.

On the other hand, fasting all the time, in theory, would then permanently slow your metabolism and counteract the benefit of intermittent fasting. At any given time then, the body would store as many calories as possible due to the fact you are underfeeding it. This would defeat the objective of intermittent fasting. Be sure to consult your dietitian when attempting your first intermittent fast.
